Complex Instruction Team Product (CITP) learning model is one of the creative-innovative learning models which is assumed to be able to empower scientific attitudes and learning outcomes of students. This study aimed to determine students’ scientific attitudes and cognitive learning outcomes by implementing CITP learning model. This research used one-group pretest-posttest design. The sample was 18 tenth graders of academic year 2017/2018 of State Senior High School 6 of Ambon, Maluku Province. The data was analyzed using N-Gain test which then continued with dependent samples t-test. This result indicated that the highest achievement of students’ scientific attitudes were honesty and creativity (54). Meanwhile, the N-Gain score of students' cognitive learning outcomes was 0.61. In addition, the results of paired samples t-test show that there was a significant difference (p<0.05) between the students’ cognitive learning outcomes before and after the application of CITP learning model. This means that the application of CITP learning model can improve students’ scientific attitudes and cognitive learning outcomes.

The mitotic index of the roots of pigeon pea can be the basis for determining the growth of pigeon pea. The purpose of this research was to determine the time of root cell division, to observe the mitotic phases, and to determine the mitotic index of pigeon pea root cells. The preparation of the pigeon pea was carried out for 4 days to grow the roots. The roots were cut off at 08.00, 08.15, and 08.30 WIT (Eastern Indonesian Time). The roots were cut 0.5-1cm. Carnoyâ€™s solution was used as the fixative solution using the Squash technique. The prepared roots were then observed using an Olympus cx-22 microscope and an OptiLab camera with a magnification of 100x40. The data were descriptively analyzed to describe the images of mitotic phases and the mitotic index presentation in the root cells of pigeon pea. The results of this research showed that the cell division of the pigeon pea roots began at 08.00 WIT, which was marked by the presence of a lot of prophase. The next phases that appeared were prometaphase, metaphase, and anaphase which occurred from 08.15 to 08.30 with different numbers. The highest mitotic index occurred at 08.15, when most of the root cells underwent metaphase. This study succeeded in revealing that the optimum time for pigeon pea root cell division is 08.15 WIT. In the future, this research can help pigeon pea farmers in Southwest of Maluku to carry out vegetative reproduction which is closely related to this mitotic study.

Background: Seaweed is widely cultivated in coastal areas of Indonesia, one of which can be found in Kayeli Bay, Buru Regency. One of the problems faced by farmers in cultivating seaweed in this area is that there is no division of suitable areas for cultivation land in the form of thematic maps, especially using physical-chemical parameters of waters. Methods: This activity includes several stages, namely location survey, data collection or collection and preparation of a database. Measurements of physical and chemical parameters of waters are carried out directly in the field (in situ) and in the laboratory (ex situ). The measurement parameters include temperature, brightness, wave height, current speed, pH, salinity, DO, nitrate and phosphate. To create a thematic map of land suitability, the ArcGis application was used. Results: Most of the physical and chemical parameters of the waters are still suitable for seaweed cultivation, except for temperature and phosphate. The results of land suitability evaluation/analysis based on water physical-chemical parameters produce two land suitability categories, namely suitable (S2) and very suitable (S1). The category corresponds to an area of 110.2 ha or 29% and very corresponds to an area of 269.8 ha or 71%. Conclusion: The thematic map of Kayeli Bay waters, Buru Regency shows that the suitability of seaweed cultivation land is divided into two categories, namely suitable at 29% and very suitable at 71%. However, the temperature and phosphate parameters at the time of measurement were in the category not suitable for seaweed cultivation.

Gayam (Inocarpus fagifer) is one of the members of the angiosperm flora in Ambon City, Indonesia, that grows and develops at various altitudes. This research aimed to analyze the leaf and stomata morphometrics of these plants in the Aer Louw and Ema Village areas. Leaf samples were taken from the upper, middle, and lower strata and considered as replicates. The morphometric characteristics were measured manually using millimeter block paper and the formula for calculating leaf ratio. Furthermore, the stomata were stained using the direct incision method and safranin. The incision results were analyzed using an Olympus CX23 microscope at 400x magnification. The measurement and observation were analyzed descriptively and correlatively. The results showed that the average leaf width and length, also the midrib length were greater in Aer Louw Village than in Ema Village; while the leaf tip and stalk length were greater in Ema Village than in Aer Louw Village. The characteristics of stomata length and width in Ema Village were greater than in Aer Louw Village; otherwise, the number, index, and density of stomata in Aer Louw Village were greater than in Ema Village. Meanwhile, the correlational analysis showed that the environment influenced the variations of leaves and stomata. Therefore, the variations of leaves and stomata in the areas could predict plant adaptations to different environments.

Tongkat langit banana fruit is used as food and for the treatment of several types of diseases, while the peel is not used, even though the peel contains nutrients that are very important for the body such as carbohydrates, vitamins and minerals. Tongkat langit banana peels can be innovated into jam with the addition of sugar. To find out the sugar concentration that is suitable for the good quality of tongkat langit banana peel jam, it is necessary to carry out an organoleptic test. Apart from organoleptic testing, a chemical test was also carried out on jams. Methods: This research was conducted from January to February 2020. Organoleptic tests were carriedout on 20 semi-trained panelists and then a proximate t analysis was carried out following the SNI 3746: 2008 method. The research data were analyzed descriptively using graphic presentation. Rsults: The parameters assessed in the organoleptic test on jam made from tongkat langit banana peels were color, texture, taste, aroma and level of preference. Apart from organoleptic testing, chemical tests were also carried out on banana peel jams, which included testing for moisture, ash content, fat content, protein content and carbohydrate content. Conclusion: The organoleptic test shows that the higher the sugar concentration in the jam, the lower the color quality of the jam, the more the sweetness of the jam, the more the thickness of the jam increases the distinctive aroma of jam, then the jam that is very popular with panelists is jam with sugar concentration. 50%. The chemical test results showed that the jam with a sugar concentration of 50% contained 25.97% water content, 0.86% ash content, 30.99% carbohydrate content, 0.30% fat content, and 0.13% protein content.
